AE-1328 - Copeland Digital Compressor Controller
AE8-1328 R5March 2011AE8-1328 R5Copeland Digital Compressor ControllerIntroduction The Digital Compressor Controller is the electronicsinterface between the Copeland Scroll Digital compressor or the Copeland Discus Digital compressorand the system controller. The Digital CompressorController is designed only for single phase CopelandScroll Digital compressors and three phase CopelandScroll Digital and Discus Digital compressors. (ReferenceEmerson Climate Technologies AE21-1319, AE4-1357and AE21-1355 for details on the digital compressor.)The system controller supplied by the OEM measurestemperature, pressure or humidity to calculate theneeded compressor capacity and communicates thatcapacity to the Digital Compressor Controller via ananalog signal.For systems that need an accurate suctionpressure reading, the Digital CompressorController is able to smooth out the pressureswings associated with loading and unloadingthe compressor. A pressure transducer input is“filtered” by using the unloader control algorithmto output a smooth suction pressure signal. For systems that include a compressor vaporinjection solenoid valve, the compressor controllerenergizes this valve whenever the compressoris running.SpecificationsThe Digital Compressor Controller provides control,protection and diagnostics for the digital compressorsystem. The type of compressor and the applicationdetermine the version of Digital Compressor Controllerthat can be used. See Tables 1, 2 3 and 4 for partnumber details. The Digital Compressor Controller “modulates”or cycles the unloader solenoid in an on/offpattern according to the capacity demand signalfrom the system controller. The compressor contactor coil is controlledbased on the capacity demand from the systemcontroller and the presence of any compressortrip or lock out conditions. Width: 2.0”(51 mm)Height:4.0”(102 mm)Depth: 6.0” (153 mm)The compressor is protected against highdischarge temperature by a discharge temperaturethermistor. If the maximum temperature limit isexceeded, the Digital Compressor Controller willprotect the compressor by turning it off.Operating Temperature:-40 F to 150 F(-40 C to 65 C)Storage Temperature:-60 F* to 175 F(-49 C* to 80 C)Seven ALERT codes are displayed indicatingan abnormal system or compressor condition.Depending on the severity of the code, theDigital Compressor Controller will shut down thecompressor or run the compressor in a limitedcapacity.Supply Voltage:19-28VAC, 48-62HzSupply Power:2 VA maximumUL Requirements:For power supply:use only with Class 2circuits, File #SA32917After each compressor shut down event, in somedigital controller module versions a two minuteanti-short cycle delay timer is active preventingthe compressor from restarting. This is indicatedby a flashing green light. See Table 1 for versionswith this feature.Enclosure ProtectionIP20, NEMA1 2010 Emerson Climate TechnologiesPrinted in the U.S.A.*MIL-STD-810F, Method 502.4, 4.5.21
AE8-1328 R5InstallationFour #10 self tapping sheet metal screws, at least½” length, are required for installation. The maximummounting screw torque is 20 in.lbs. Locate theDigital Compressor Controller inside the electricalenclosure near the compressor contactor (wirerouting for compressor power wiring will be easierin this position). The maximum wire terminal screwtorque is 7 in. lbs. The Digital Compressor Controllerwill operate in any mounting orientation where thegreen POWER LED is at the top. Mount the DigitalCompressor Controller so all LEDs are visible froma comfortable viewing position.A service panel label (Form 052-2401-00) describingthe terminals and ALERT flash codes is included witheach Digital Compressor Controller. This label shouldbe in a visible location for the technician when he istroubleshooting the system. See Figure 5.Figure 1Digital Compressor Controller 543-0024-00, -01Compressor Wiring(See Figure 3)The Digital Compressor Controller senses compressormotor current for diagnostics and protection. Thecompressor motor leads must be run through theholes in the plastic housing for a current transformerto sense motor current.Single Phase Compressors: the compressor’s run(R), common (C) and start (S) wires must be routedthrough the holes in the Digital Compressor Controllermodule marked “R,” “C” and “S.” The run capacitor maybe located on either side of the Digital CompressorController module.Three Phase Compressors: the compressor’s T1, T2and T3 wires must be routed through the holes in theDigital Compressor Controller module marked “T1,”“T2” and “T3.” The Digital Compressor Controllermodule is phase insensitive and will not detect reversephasing of the compressor.Figure 2Digital Compressor Controller 543-0086-01Low Voltage Terminals24COMModule Common24VACModule PowerC1Demand Input –RecommendC2Demand Input Shielded CableP1Pressure CommonP2Pressure InputP3Pressure Power 5VDCP4Pressure ShieldP5Pressure Output –P6Pressure Output T1Discharge Temp SensorT2Discharge Temp SensorNOTE!Do not bundle low voltage wires with compressorpower or high voltage wires.{NOTE!Attach cable ties through loops on side of thehousing for wire strain relief. 2010 Emerson Climate TechnologiesPrinted in the U.S.A.2

For best signal resolution, the smallestacceptable pressure transducer range for the refrigerantshould be used. The Digital Compressor Controllerprovides a precision source 5VDC for the pressuretransducer to accurately measure the pressure. This5VDC source is capable of sourcing a maximum of10mA(P5, P6) System Pressure OutputIf a pressure transducer is connected to the SystemPressure Input terminals, the System Pressure Outputprovides an analog output of the filtered suctionpressure. The Digital Compressor Controller “filters”this suction pressure by using the unloader capacityalgorithm to smooth the pressure fluctuations measuredby the suction pressure transducer. The output of0 – 5VDC corresponds to the range of the pressuretransducer connected to the System Pressure Inputterminals. This output is capable of sourcing a maximumof 10mA.NOTE!To avoid damaging the Digital Compressor Controller donot connect wires to terminals C3, C4, T3, T4, T5 or T6.(24VAC, 24COM) Digital CompressorController PowerThe power supply for the Digital Compressor Controlleris 19-28VAC, 48-62Hz. The maximum load is 2 VA. The24VAC phasing for the Digital Compressor Controllermust match the system controller to avoid a transformershort circuit condition because the two controllers havetheir commons connected together. Twenty-four voltpower to the module must be on anytime the unit is onand should not be interrupted by any control. Centertap transformers are not to be used.(T1, T2) Discharge Temperature InputThe Discharge Temperature Input is a thermistor input.There is no polarity requirement for the thermistor.For thermistor signal wiring, short wire runs arerecommended. For 3D Discus Digital and Scroll Digital,the cut out temperature is 268 F (131 C) and the cutin or reset temperature is 250 F (121 C). For the 4DDiscus Digital, the cut out temperature is 310 F (154 C)and the cut-in temperature is 267 F (130 C). See Table4 for thermistor temperature/resistance values.(C1, C2) System Controller DemandController Demand is an analog input signal fromthe system controller to the Compressor Controller,proportional to the capacity required from the compressor.Controller Demand is a 1-5VDC input where 1.0VDC is0% capacity and 5.0VDC is 100% capacity. When thesignal falls below 10% capacity (1.25VDC on decreasingdemand) the Digital Compressor Controller will shutdown the compressor. When the signal rises above10% capacity (1.44VDC on increasing demand) andthe anti-short cycle timer inherent in some controllers(see Table 1) has timed out, the Digital CompressorController will start the compressor again. See Figure4 for a graphical representation. The maximum inputvoltage for C1, C2 is 5.3 VDC.(A1, A2) Alarm RelayThe Alarm Relay output is a normally open, dry contactrelay output. The maximum operating voltage for thisrelay is 250VAC or 30VDC and the maximum load is 3 A.During an alarm condition, the relay contacts close untilthe alarm condition ceases or power is turned off.(M1, M2) Compressor ContactorThe compressor contactor output is a triac output. Themaximum continuous contactor coil load is 0.5Aand the peak inrush current is 6A. The maximumcoil operating voltage is 24 - 250VAC. This output isincompatible with DC coil voltages. The compressorcontactor is energized when there are no ALERTconditions and the demand signal is greater than1.44VDC.NOTE!During normal unit operation the voltage to C2 mustbe above 0.5 volts. The voltage to C2 should never becompletely interrupted while the unit is on.(P1, P2, P3, P4) System Pressure InputIf a pressure transducer is used with the CompressorController, the System Pressure Input is a measurementof the system suction pressure. For pressure transducersignal wiring, short wire runs and shielded wiring are 2010 Emerson Climate TechnologiesPrinted in the U.S.A.(L1, L2) Control PowerNOTE!Control Power supplied to Digital Compressor Controller3
AE8-1328 R5must be the same voltage as the compressor contactorcoil, unloader solenoid and vapor injection solenoid.Compressor RunningThe loaded/unloaded cycle always equals either 20seconds or 15 seconds depending on the controllermodule. The loaded sequence always precedes theunloaded sequence. Capacity modulation is achieved byenergizing and de-energizing the solenoid valve. Whenthe solenoid valve is de-energized, the compressorcapacity is 100%. When the solenoid valve is energized,the compressor capacity is zero. Therefore, the capacityachieved is the time average capacity, which is avariable from 10 – 100%.The Control Power requirement is a single phase, 19250VAC, 48-62Hz source. The control power must beisolated with a transformer from the mains powersupply. The maximum load on the control powercircuit is 1.5A based on a motor contactor, unloadersolenoid and vapor injection solenoid connected to theCompressor Controller.(U1, U2) Unloader SolenoidThe Unloader Solenoid output is a triac output. Themaximum continuous solenoid load is 0.5A and the peakinrush current is 6A. The maximum solenoid operatingvoltage is 250VAC. This output is incompatible with DCsolenoid voltages. The unloader solenoid is energizedin an on/off pattern to deliver the capacity requested bythe demand signal.Example of 20 second cycle: If the solenoid is deenergized (compressor loaded) for four seconds,then energized (compressor unloaded) for sixteenseconds, the resulting capacity will be 20% of full loadcapacity. See Table 2. Example of 15 second cycle: Ifthe solenoid is de-energized (compressor loaded) forthree seconds, then energized (compressor unloaded)for twelve seconds, the resulting capacity will be 20%of full load capacity. See Table 3.(V1, V2) Vapor Injection SolenoidThe Vapor Injection Solenoid output is a triac output.The maximum continuous solenoid load is 0.5A. Themaximum solenoid operating voltage is 250VAC and thepeak inrush current is 6A. This output is incompatiblewith DC solenoid voltages. The vapor injection solenoidis energized whenever the compressor contactor isenergized.Digital Compressor Controller LEDsPOWER LED (green) – indicates voltage is present atthe 24VAC power terminals. When the anti-short cycletimer is active, the green LED will flash.UNLOADER LED (yellow) – indicates the unloadersolenoid status. This LED is on when the unloadersolenoid is energized.Compressor Start And Shut DownThe Digital Compressor Controller always unloadsthe compressor for 0.1 seconds at each startup. Afterthis brief unloading period, the unloader solenoid willbe deenergized and the compressor will run loadedaccording to the level of the Demand input signal.Each time the compressor shuts down, the DigitalCompressor Controller will run the compressor unloadedfor 0.5 seconds. Energizing the unloader solenoid forthis period of time will allow the discharge and suctionpressures to equalize, minimizing scroll reverse rotation.ALERT LED (red) – communicates an abnormal systemcondition through a unique flash code. The ALERT LEDwill flash a number of times consecutively, pause andthen repeat the process. The number of consecutiveflashes, defined as the Flash Code, correlates to aparticular abnormal condition.Flash Code TroubleshootingWhile each ALERT code is active, the alarm relaycontacts (A1 and A2) are closed. The ALERT code willremain active and the alarm relay contacts closed untilthe reset conditions have been met or 24VAC power hasbeen cycled off and on. All Flash Codes except Code6 and 8 result in the compressor contactor, unloadersolenoid and vapor injection solenoid being deenergized.Flash codes 3, 4, 5, and 9 activate the two minute anticycle timer. Flash code 2 activates the 30 minute timer.All LEDs flashing at the same rate indicates 24VACsupply is too low for operation. All LEDs on solid atthe same time indicates Digital Compressor Controllerfailure. 2010 Emerson Climate TechnologiesPrinted in the U.S.A.4
AE8-1328 R5Whenever power is cycled off and on, the current FlashCode and all internal counters are reset.The Digital Compressor Controller will deenergizethe compressor contactor and vapor injectionsolenoid. The alarm relay contacts will close.Flash Code 1 - Reserved for future useIf a low pressure cut-out device is used, thecompressor could short-cycle depending on the cutin and cut-out pressures and system configuration.This could be interpreted as a Locked Rotor faultby the Digital Controller and the compressor willget locked out.Flash Code 2 - High Discharge TemperatureThe discharge temperature thermistor has measureda temperature above 268 F (130 C) or the thermistoris short circuited (jumpered out).The Digital Compressor Controller will deenergizethe compressor contactor and vapor injectionsolenoid. The alarm relay contacts will close.This code results in a lockout and can only be resetby cycling the 24VAC power off and on.Flash Code 5 - Demand Signal LossThe demand signal input has dropped below 0.5VDC.The demand input signal wire may be disconnectedor the system controller providing the signal maynot be powered.The compressor will be allowed to restart after a 30minute delay and after the thermistor temperatureis below 250 F (120 C). The flash code and alarmrelay contacts will be reset after the compressor hasrun for 60 uninterrupted minutes without any otherALERTs.The Digital Compressor Controller will deenergizethe compressor contactor and vapor injectionsolenoid. The alarm relay contacts will close.If five high discharge temperature ALERTs haveoccurred within four hours, the Digital CompressorController will lock out the compressor. The lockoutcan only be reset by cycling the 24VAC power offand on.Once the system controller demand signal input hasrisen above 0.5VDC, the ALERT code and alarmrelay output will reset. If the demand signal is above1.44VDC and the anti-short cycle timer has timedout, the compressor will restart. There is no lockoutfeature for this ALERT.Flash Code 3 - Compressor Protector TripThe demand signal from the system controller isgreater than 1.44VDC and there is no compressorcurrent detected. This could be due to thecompressor’s internal overload protector beingopen, fuse or breaker open, power disconnected tocompressor contactor, compressor power wiring notrun through Digital Compressor Controller currenttransformer port or a compressor contactor failure.Flash Code 6 - Discharge Thermistor FaultThe Digital Compressor Controller is not receivinga signal from the discharge temperature thermistor.The thermistor may be missing, disconnected or awire is broken.The Digital Compressor Controller will deenergizethe compressor contactor and vapor injectionsolenoid. The alarm relay contacts will close.The alarm relay contacts will close and the DigitalCompressor Controller will not increase the capacityof the compressor beyond 50% loading.The Digital Compressor Controller will wait forthe anti-short cycle timer to time out and if thesystem controller demand signal is still greater than1.44VDC, energize the compressor contactor again.If compressor current is detected on the restart, theALERT code and alarm relay output will reset. TheDigital Compressor Controller will attempt to restartcompressor as long as the system controller demandis above 1.44VDC. There is no lockout feature forthis ALERT.This ALERT code and alarm relay output are resetby reconnecting the thermistor.Flash Code 7 - Unloader Solenoid FaultReserved for future useFlash Code 8 - Compressor Contactor FaultCompressor current is detected when the systemcontroller demand signal is below 1.44VDC. Thecompressor contactor may have welded contactsor the contacts may be mechanically jammed. Thecompressor will continue to run in this condition sincethe Digital Compressor Controller cannot open thecompressor contactor.Flash Code 4 - Locked RotorA locked rotor condition in the compressor issensed by the Digital Compressor Controller on fourconsecutive start ups within a 20 second period. 2010 Emerson Climate TechnologiesPrinted in the U.S.A.5
AE8-1328 R5Input TestsThe Digital Compressor Controller will energizethe compressor contactor and vapor injectionsolenoid. The alarm relay contacts will close. Theunloader solenoid will remain energized causing thecompressor to run unloaded as long as the systemcontroller demand signal is less than 1.44VDC. If thesystem controller demand is greater than 1.44VDC,the unloader solenoid will deenergize causing thecompressor to run loaded.Thermistor Input – disconnect the discharge temperaturesensor wires from terminals T1 and T2. If functioningnormally, the Digital Compressor Controller should displaya Code 6 unless a previous ALERT code was present.Demand Input – disconnect the System ControllerDemand signal wires from C1 and C2. If functioningnormally, the Digital Compressor Controller shoulddisplay a Code 5 unless a previous ALERT code waspresent.The ALERT code and alarm relay output are resetwhen current is no longer detected while systemcontroller demand signal is below 1.44VDC.Output TestsFlash Code 9 - Low 24VAC SupplySupply voltage to the Digital Compressor Controllerhas dropped below 18.5VAC.Contactor Output – while the Digital CompressorController is powered off (no supply voltage to 24VACand 24COM), disconnect the System Controller Demandsignal wire from C1 and C2. Add a jumper wire from P3to C2 and a second jumper wire from P1 to C1. Reapplypower to 24VAC and 24COM. If functioning normally,a voltmeter should read the same voltage across M1and M2 as is measured across L1 and L2, unless anALERT code is present.The Digital Compressor Controller will deenergizethe compressor contactor, unloader solenoid andvapor injection solenoid. The alarm relay contactsmay close if the voltage is high enough for the alarmrelay to pull in.The ALERT code and alarm relay output are resetwhen the supply voltage to the Digital CompressorController rises above 19.5VAC.Unloader Output – while Digital Compressor Controller ismodulating the unloader solenoid, a voltmeter should readthe same voltage across U1 and U2 as is measured acrossL1 and L2 whenever the yellow “Unloader “LED is lit.OEM TestingThe Digital Compressor Controller can remain incircuit during factory hi-pot testing. The maximumhi-pot test voltage that should be applied betweenground and the 24VAC Low Voltage Inputs andOutputs is 600VAC. The maximum hi-pot testvoltage that should be applied between the HighVoltage Control and High Voltage Outputs is2500VAC. The normal leakage current should beless than 200 microamps.Demand Cooling with Copeland Digital CompressorControllerThe digital compressor controller has its own dischargetemperature protection. However, for applications requiringDemand Cooling, the Demand Cooling module shouldhave primary control of the temperature protection.To ensure the Demand Cooling system functionsappropriately, jumper the T1 and T2 inputs on the DigitalCompressor Controller, with a 5kOhm, 1 Watt resistor.Testing the Installed Digital Compressor ControllerFor more information regarding Copeland DemandCooling, refer to AE4-1327, Economized Vapor Injection(EVI) Compressors, and/or AE4-1287, Copeland DiscusDemand Cooling.Once installed, the Digital Compressor Controller canbe tested to verify it is working properly. In each test,24VAC must be supplied to 24VAC and 24COM. For theoutput test, 24-250VAC must be supplied to L1 and L2. 2010 Emerson Climate TechnologiesPrinted in the U.S.A.6
